GridbagLayout Problem 1

[k4ghg]

Hi - I am trying to create a startup screen (from and old splashscreen) with a disclaimer that people need to accept before they continue. There is a graphic on the left and next to it there is text that later expands under the graphic. In the future I will add two buttons.

I use a Gridbaglayout with the graphic in a Jlabel and the text divided into two areas one next to the graphic and the other below. But the code does not seem to work.

First the graphic does not stay anchored to the corner and second only the label appears.

Would someone please look at the code and tell me what I am missing.

Thanks...Ronnie

c.anchor = GridBagConstraints.NORTHEAST;

I have never used GridBagConstraints. but I found if you change

c.anchor = GridBagConstraints.NORTHEAST;

to

c.anchor = GridBagConstraints.WEST;

Then you can see the picture. Maybe you didn't set the width and height of NORTHEAST.
